Question

Use a 8%significance level. Assume the results come from a random sample, and if the sample size is small, assume the underlying distribution shape is relatively normal. Also the population standard deviation is unknown. Test under alternative hypothesis that μ>10 using the sample results: mean is 13.2, s=8.7, with n=12. Answer the following: Part A: What is the test statistic? (round to the second decimal place) [ Select ] ["1.27", "-2.73", "-1.45", "-0.67", "0", "-1.27", "0.67", "1.45", "2.73"] Part B: What is the pvalue? [ Select ] ["0.5", "0.387", "0.289", "", "0", "0.114", "0.045"] Part C: What is the decision? [ Select ] ["Do not Reject Ho (Retain Ho)", "Reject Ho"]
